Title: Artificial and natural structures
IPC: E04G23/02
Filed: 1973-07-13
Abstract: 1399510 Forming or repairing structures by adhesive BALFOUR BEATTY & CO LTD 11 Oct 1973 [11 Oct 1972 I Nov 1972 13 July 1973] 46909/72 50321/72 and 33559/73 Headings E1F and E1S A fissured structure, e.g. a cracked bridge pier or a pile of bricks, is strengthened by sucking a hardenable liquid or semi-liquid material, e.g. a resinous grout or a cement grout, through the structure after evacuating air and any fluid from the structure which is at least partially surrounded by a substantially fluid-tight enclosure, e.g. a flexible shroud or a coating. A brick bridge pier (Fig 3) is repaired using a shroud 15 in combination with a synthetic resin coating 14, the edges of the shroud being sealed against the structure, and the shroud being evacuated using a vacuum pump or air compressor/venturi arrangement. The structure is allowed to stand for, e.g. three hours to allow it to dry out, and then grout is sucked through from the lower pipe shown. The grout may include polyester resin or epoxy resin, and may be reinforced.  A brick wall (Fig 4) may be strengthened in a similar way, a dry wall being erected initially, and then impregnated with polyester resin inside a transparent polythene shroud 32. Spacers can be employed between the bricks if desired. If a high viscosity/high surface tension grout is employed, a pulsating vacuum may be employed, e.g. twelve pulsations per minute to achieve fuller impregnation. Alternatively the degree of vacuum may be initially low and increased when impregnation is almost complete to remove air bubbles. An archaeological ruin (Fig 5) comprising stone blocks may be repaired by replacing old blocks with new ones 52 with spacers between, and a wire 53 is employed, through which an electric current is passed, to speed the setting of the grout. The wire is left in as reinforcement. The wire passes through fluid-tight seals on the shroud.  Inlet fitting adaptors are illustrated in Fig 6 (not shown here) and Fig 7, the latter incorporating a cutter 76, which is rotated to form a hole in the shroud.

Title: Improved spark plug for internal combustion engines
IPC: H01T13/46
Filed: 1945-12-12
Abstract: 605,013. Sparking-plugs. GENERAL MOTORS CORPORATION. Dec. 12, 1945, No. 33564. Convention date, March 17. [Class 7 (iv)] The central electrode is in two portions 26, 38 with a spark-gap 36 between them in a bore of the insulator and the lower portion is sealed in the insulator by a gastight seal 30, 32, 34 and the upper portion held in place by glass 37 which is air pervious, the seal and the glass being bonded to the bore of the insulator. The portion 32 of the gastight seal forms a resistance element: The spark-gap comprises discs 42 of a material such as nickel spaced by an insulating sleeve 40, the discs having brazed to them tungsten contacts 44. Alternatively, to using tungsten for the contacts, platinum, platinum tungsten alloy or nickel or other alloys may be employed, or copper may be used when the operating temperatures are low. The seals 30 and 34 are conductive glass seals preferably of a fused mixture of 55 parts powdered copper, 45 parts borosilicate glass and three parts of a binder such as hydrogenated cottonseed oil. The resistor 32 is preferably of 62.4 per cent borosilicate glass, 25.2 per cent fluorspar, 7.8 per cent magnesium borosilicate glass and 4.6 per cent carbon black. The glass 37 may consist of borosilicate glass, but a glass having the following composition is preferred : SiO2-34 per cent, B2O3-28 per cent, PbO-29 per cent, Al2O3- 7 per cent, Na2O-2 per cent. This glass has no binder since during the fusing in the insulator bore a binder causes the deposit of a carbon film on the insulating sleeve of the spark-gap. When the binder is omitted, the powdered material is difficult to handle in the small amounts required. To overcome this, pellets are formed from the composition of the seals 30 and 34, the binder being used to form the powder into pellets and the pellets are sintered preferably in a hydrogen atmosphere at from 1500‹ to 1700‹ F. for from 15 minutes to one hour. This process substantially frees the pellets from the binder. It has been found that either all pellets or all powdered material is necessary for the seals 30, 32, 34. The preferred composition for the glass 37 produces a finely-cracked glass which permits seepage of air into the auxiliary gap. Instead of using a finely-cracked glass, a vent may be provided. The lower section 26 of the electrode may be as shown with a core 28 of copper or other good heat-conducting metal, or it may comprise a platinum tip seating in the bore of the insulator and in connection with a main portion of silver cast in place. The Specification as open to inspection under Sect. 91 states that compressed powdered talc may be used in place of the glass seals. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,113,005. Thermoelectric devices. WESTINGHOUSE ELECTRIC CORPORATION. 27 July, 1966 [9 Aug., 1965], No. 33711/66. Heading H1K. [Also in Division B3] A self-spacing solder which has insoluble metallic particles dispersed through a soft solder component, the particles being of selected size in order to maintain the required spacing of surfaces to be soldered together is used to bond a thermoelectric body to one or more metallic contacts. The solder compositions are as given in Specification 1,112,693. Thin discs 28, 40, and 46, of the solder are employed to bond a thermoelectric pellet 22 to metallic contacts 18, 30 and to bond the contact 30 to the end of a braided copper lead 42. The pellet 22 may be of P-type germanium bismuth telluride or N-type lead telluride; germanium telluride, zinc antimonide and other metallic sulfides, selenides, antimonides and tellurides may similarly be bonded. The contacts may be of iron, cobalt, nickel, nickel alloy, copper or stainless steel. Tin-coated iron contacts are referred to. The solder may similarly be used to bond two components to form a thermoelectric couple (Fig. 2, not shown). Soldering is effected by placing the assembled devices in an oven or furnace and heating to a temperature within the range 235 C.-425 C. with a stream of hydrogen passing through the furnace. In Example 3 reference is made by way of comparison to two similar thermoelectric couples, one having hard solder joints the solder comprising an alloy of gold and zinc and the other having a nickel phosphide diffusion bonded joint. In Examples 4 and 5 the solder used is pure lead with iron particles and no phosphorus is included.

Title: Complex metal oxide minerals treatment
Inventor: ARCHAMBAULT MAURICE
IPC: C01G53/10
Filed: 1956-11-08
Abstract: Nickel magnesium hydrated silicates such as garnierite are treated with sulphur trioxide gas or a catalytically activated mixture of sulphur oxides and oxygen or air at 300 to 900 DEG C. to form water-soluble sulphates of nickel and magnesium which are recovered by leaching.  The treatment gas is preferably derived from sulphur dioxide and air which has been passed over a catalyst such as platinised asbestos, iron oxide or vanadium oxide at 425 to 600 DEG C.  The sulphur dioxide may be roaster effluent gas from a pyrrhotite, pyrite or sphalerite roasting.  The reaction temperature is preferably maintained below 750 DEG C. to prevent decomposition of the nickel sulphate formed and the hydrated silicate is preferably contacted countercurrently with the incoming sulphur oxides. Reaction may be effected in rotary, multiple hearth or fluidised bed reactors.  Leaching may also be effected in countercurrent manner and the nickel may be separated from the sulphate solution formed by electrolytic decomposition. Magnesium sulphate may then be recovered by evaporation. According to a typical example garnierite was treated as a static bed with a mixture containing approximately 4 parts of sulphur dioxide and 3 parts of wet air which had been passed over a vanadium oxide catalyst at 450 DEG C.  The reaction temperature was 700 DEG C.  The reaction product was cooled and leached to recover nickel and magnesium sulphates.  Specification 566,013 is referred to.
